Faglige interesser

Jeg jobber med flere aspekter av multiskalainteraksjonen mellom magnetosfæren og ionosfæren. Jeg er særlig interessert i innvirkning av storskala feltparallele strømmer på mellomstore og småskala ionosfæriske strukturer.

Jeg er involvert i driften av m-NLP-instrumentet ombord på den norske NorSat-1-satellitten som gir uovertruffen data om småskala ionosfæriske strukturer relatert til GNSS-scintillasjoner.
